Build Options

The packaging methods included in this repository aim to minimize the package size while ensuring performance, with asm and NEON enabled. For specific build options, refer to the build scripts in the build_script directory.

Build

Prepare

• Install git
• Install Android NDK (tested with ndk22, ndk25, ndk26, ndk27, ndk28), do not use NDK23!
  • Tested with all NDK versions on macOS and Ubuntu 20.04+
• Install yasm, nasm (via brew install nasm yasm or apt install nasm yasm -y...)

Perform build

1. $ export NDK=/path/to/your/android-ndk
2. $ ./build_android.sh
   • Use ./build_android.sh --ffmpeg 4.4.4 --x264 31e19f92f00c7003fa115047ce50978bc98c3a0d to build the specific version
3. $ cd jni && $NDK/ndk-build
4. The libffmpeg.so is in the folder libs
